What are the purpose of the left and right side crossover mirrors?

The purpose of the left and right side crossover mirrors is specifically designed to enhance the driver's ability to see the danger zone areas on both sides of the bus. These mirrors are strategically positioned to eliminate blind spots that can occur when the bus is in motion or when children are boarding or disembarking. By providing a clear view of the areas immediately surrounding the bus, these mirrors help ensure the safety of students and allow the driver to detect potential hazards that might not be visible with standard mirrors alone. This feature is crucial for preventing accidents and ensuring that the driver has a full understanding of the environment surrounding the bus, particularly during stops where children are present and may be at risk.
